Notches are cut in a "Z"-section closure to be installed across seams on a standing seam metal roof by means of a tool which punches holes in the central web of the closure. The lower flange of the closure is subsequently cut manually to finish the notch. The tool's die surfaces correspond in shape to that of the closure, and the punch and die are aligned so that the elongate hole they make in she central web extends to the bottom of the web.
